使用 ifupdown 无法找到桥接设备

使用 ifupdown 无法找到桥接设备

请注意，我使用的是 Void Linux。

这是我的/etc/network/interfaces.d/br0文件：

auto br0
iface br0 inet dhcp
    bridge_ports eth0
    bridge_stp off
        bridge_waitport 0
        bridge_fd 0

但是在启动时我收到此错误：

ifup: failed to bring up br0

我已经确认我已经bridge-utils安装了。我不知道这里的问题是什么。我将不胜感激的帮助。

（这实际上是一个“评论”，而不是答案，但它不适合评论部分）

似乎ifup没有“在幕后”创建桥接界面。

我希望它能做到这一点：

ip link add name brLAN type bridge
ip link set brLAN up
ip link set eno1 master brLAN
ip link set eno1 up

如果网桥使用 dhcp 那么：

dhclient brLAN
